Much like any high-school student, a diamond is marked with a grade when it comes out the other end of the cutting process. There are two separate organizations running the examination show, GIA and AG:s. And just like in high-school, where you get graded on everything from math sac longchamp pas cher to gym, a gemstone also has its different subjects.

Diamonds - From Rough Cut To Precious Gem Diamonds pass through many steps of the ladder commonly called the chain of supply. Every hand involved in this process, also means a step up in market price for the finished retail item we achingly lust for when we are out window-shopping.

The four C's of the trade is the holy grail of this business and a template to judge the quality of a gemstone that everybody has to subject themselves to. The four C's meaning: cut, color, clarity and carat.

The number one priority for a jewelry appraiser is looking at the so called table of the stone, which is the top part of it where the facets are easiest to judge. Depending on what type of cutting process the gem has been put through, that area varies in size accordingly. The biggest flat top area on a gemstone is called the emerald cut. To perform this type of cut, you really need a stone that can stand the test of time and that can pass under the most scrutinizing magnifying glass belonging to the most thorough Antwerpen appraiser. Because it is from this area, the table, that an appraiser targets his critical eye when he is looking for facets. So therefore, a stone where the color or clarity is not holding up to industry standard, will immediately be discovered in an emerald cut.

Polish and symmetry are judged by the GIA in a falling scale from "excellent", "very good", and just plain old "good". If a stone does not measure up to good it does not get their diploma, instead they are sent straight away to be used in industry equipment. AGS also grade in a falling scale from ideal (D) down to good.

GIA then continues to grade the longchamp soldes color, where the top student gets awarded with a big D and then the color grading of a gemstone trails down the full list of the alphabet. A stone marked with a grade from D to K is practically colorless, which of course is what every appraiser is looking for sitting there with their eye pressed against the loupe, but to find one is about as common as winning the high price on the national lottery.

After that they move on, judging a gemstone on its clarity and the carat so when it is installed in the most beautiful engagement ring you have ever seen, you can ask your designated jeweler to see the standard paperwork for any given stone. If your jewel is graded with a 0 from AGS it means the clarity is completely flawless, inside and out and every which way you look at it.

Now go out searching for those grade A diamonds.
